ELECTROLYTIC APPARATUS.

Application filed February 18, 192?. Ferial Ho. 159,3a5.

This invention relates to an electrolytic apparatus, the general object of the invention being to provide means for supporting the plates to be treated in a vertical position while they are being passed through the electrolytic tank, 'ith means for making the electrical connection at the upper edges of the plates while their lower edges are engaging grooved power pulleys which give the plates their movement.

'Another object of the invention is to provide insulated rods at the top of the tank and extending longitudinally thereof for supporting the anode plates which are provided with hooks at their upper edges for this purpose, the rods being connected to the circuit.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts. to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a plan view of the apparatus. ure 2 is a section on line 22 of Fig ure 1.

Figure 3 is a ure 1.

In these views, 1 indicates the tank for eining the electrolytic bath and 2 inclien... the anode plates which are suspended by their hooks 3 from the rods 4 nhich s ported by the blocks 5 of insulating mall attached to the upper edges of the ends of the tank. A plurality of grooved pulleys (3 arranged adjacent the bottom of the tank, each pulley being carried by a shaft 7 which is journaled in the tank and has one end passing through one side thereof, this projecting end receiving the pulley 8 over which the rubber belts 9 pass so that the shafts can be rotated from a suitable source of power. These grooved pulleys engage the lower edges-of the plates A to be treated and these plates are supported in vertical position in the tank by means of the rollers 10, each pair of which is carried by a vertically arranged shaft 11 supported by the brackets 12 which are fastened to'the interior side walls of the tank. These shafts are arranged in pairs,

section on line 3-3 of Fig with one shaft of each pair directly opposite the other shaft of the pair, with the rollers of the two shafts spaced apart a distance equal to the thickness of the plate to be treated so that the rollers will engage the two faces of the plate and thus support the some in vertical position.

The rollers 10 on one pair of shafts are differently situated from the rollers on another pair of shafts so that the rollers will not contact with the same parts of a plate, which would cause the rollers to interfere with the depositing of the material thereon.

The upper edges of the plates are engaged by a grooved pullev '13 which is carried by a. hanger 14- which is insulated from a support 15 attached to an upright 16 on the tank by a hinge 17 so that the support, the hanger l the pulley can be moved from over the in order to remove a plate from the or place a plate in the tank. A con- -ructor 18 is connectedwith the hanger 14 and conductors 19 are connected with the rods 4., these conductors being connected with a source of supply so that current will be supplied to the anode plates and the plates being treated in the usual manner.

From the foregoing, it.will be seen that the plates A being treated will be moved through the tank when the shafts 7 are being rotated in vertical position and parallel to the anode plates 2 so thatsaid plates will be thoroughly covered with electrolytic ma wria By having the plates stand on edge. the scale will fall oil the plates so that a product will be produced which will have less defects than where the plate is placed on side. By having the current supplied to current is automatically brollen as soon as the plate passes the pulley.

It thought from the foregoing escription that the advantages and novel features of my invention will be readily apparent.

I. desire it to be understood that I may make changes in the construction and in the con'ibination and arrangement of the several,

plate through the'grooved pulley'ld, the.

pended in the tank, a plurality of shafts journaled in the lower part of the tank, a

V grooved roller on each shaft for engaging the lower edges of the plates to be treated, means for rotatingthe shafts, vertically arranged shafts in the tank arranged in pairs, a pair of rollers on each shaft for engaging the faces of the plates to be treated, the rollers on one pair of shafts being staggered 10 with relation to the rollers on another pair of shafts, a grooved roller for engaging the upper edges of the plates to be treated, means for supporting the same, means for connecting said roller and the rods to a source of supply and an arm hinged to a part of the tank and carrying the supporting means for the last mentioned roller.

In testimony whereof alfix my signature.
